r/logitech on Reddit: Any workarounds to connect a BLE Logitech keyboard with a laptop that has Bluetooth 3.0?
June 8, 2024 -

I am trying to connect either to my Logitech MX Keys mini or MK850 keyboards to an "old" Toshiba Satellite L735 laptop (that uses Qualcomm Atheros Comm AR3011 Bluetooth 3.0) via Bluetooth and also with the Logitech Unifying Receiver and cannot get them working.

First I tried to connect via Bluetooth, but I am seeing that this might not be possible due to Bluetooth 3.0 and BLE (both keyboards use this). For this I guess I'd need to upgrade the Bluetooth hardware, right?

Second I tried connecting the MK850 keyboard using the unifying receiver using debian's (bookworm) package solaar (1.1.8+dfsg-2), everything seems to be working fine, but when I connect the USB receiver and I start typing with the keyboard the laptop (seems to crash and) shuts down immediately. If I reboot it and I have the receiver connected it keeps shutting down, so I can only run my laptop if I disconnect that USB receiver.

I saw my logs using journalctl -b -1 looking for any errors but didn't quite find anything, I will replicate this and give it another look in case I missed to spot anything useful.

In the meantime, do you have any workarounds for connecting these devices? Have you faced any similar issues as mine? Would love to hear about it and thanks in advance :)

It’s okay if it feels snug—that’s normal. Once it’s in, your computer usually takes care of the setup on its own. Look around the sides or back for a small switch and turn it on. Some keyboards also have a tiny button labeled “connect” or “pair”—press that if you see it.

r/logitech on Reddit: Secondhand K330 keyboard - how to connect?
December 12, 2024 -

Hello there! I just picked up this K330 keyboard from a secondhand store. Looks to be in very good condition (see pictures). When I looked it up, I misread that it could be connected via Bluetooth and bought it (yeah, silly mistake). The keys still sound good, nothing sticks, so I figured this could be a good back up keyboard if my current one breaks. I had no way of testing it in the store, but it was cheap enough to get.

It didn’t have a box, so I only have the keyboard itself (no accessories). It uses 2 AAA batteries so I switched out the old ones that the previous owner had left for brand new ones. Looking online, it looks like this K330 was part of a keyboard-and-mouse duo that paired wirelessly with a USB receiver. Without the original receiver, I will need a Unifying receiver but when I checked the back of the keyboard for the orange “star” symbol, it’s gray and no “K330” label (see last picture). I’m assuming I should still be able to pair it with a Unifying receiver, but I figured I’d ask on here before spending the money. Any help is appreciated. Thanks!
